Abstract: A mobile articulated head is employed on a knuckle having a mushroom shape, consisting of a roof (1) retaining a step cavity (5) in a retractable bending border, with an interposed tablet (2) in central collation seat (3) of the mushroom (4). The cavity (5) has a lower cylindrical form with collar (8), within the which the mushroom stem (9) can slide. The head components, the preliminary body (10) for the mushroom formation, as well as the spinned nail (12) and its base (13) can be obtained by means of pressing. A weakening treatment on an intermediate band of the preliminary body (10) and rolling give rise to an initial expansion of the same body upper part. The four components are riveted which compose the mobile part and the mushroom, while the nail (12) is assembled to its base (13). The preliminary body is further expanded on its head, thus determining the cap (4) of the mushroom and the inside nail crushing chamber. To the mobile part, three movements are allowed: a swinging one on the head (4), a turning motion around its stem (9) and a transfer movement between the counterposed beating crowns, i.e. the one of the hat (7) and the other (11) for the stem stabilization on the tissue.

Date Sep. 19, 1991.Flat-bottomed cavities are formed in a substrate (2) by a method comprising two etching steps: a first anisotropic etching through a mask (4) leaving exposed bands (6,8) of the substrate (2) and a second anisotropic etching through a mask leaving exposed all of the zones (Z1, Z2) to be etched. The first etching provides grooves in V form (10,12), the depth of X1, X2) which depends on the width of the bands, while the second etching increased the depth of the cavities by the same amount y, in eliminating the bands located between the grooves. Advantage: flat cavities of different depths may be obtained simultaneously.

Abstract: A personal computer characterized in that a CPU board comprising a central processing unit and a main memory, and an IO board comprising a serial interface and an FDD interface are provided in separate modules. Since the CPU board is operated by a high-speed clock and the IO board is operated by a low-speed clock, a timing conversion circuit is provided between the boards. Thereby, the CPU board and the IO board can be designed and developed separately and new products can be designed simply by changing the combination of the boards. Also, it is easy that only the CPU board is shielded electromagnetically.

Abstract: An improved aluminium-silicon alloy having relatively substantial additions of tin and bismuth is provided which is particularly wear-resistant and sufficiently self-lubricating so as to be suitable for use in a wearing component even when poorly lubricated. The relatively high tin and bismuth additions within the alloy co-operate with the other elemental additions so as to provide a sufficiently low-friction bearing surface (or self-lubricity) which significantly enhances the wear-resistant properties of the alloy. In particular, the preferred aluminium alloy is used to form a socket plate (10) which receives high-strength steel bearing members (16) within a compressor unit of an automobile air-conditioning system. The improved aluminium alloy minimizes wear and alleviates galling of the socket plate (10) during use. In addition, the improved aluminium alloy is also characterized by good strength and sufficient ductility so as to permit swaging of the socket plate (10) formed from the alloy around respective balled ends (14) of the high-strength steel bearing members (16).
